Civilization V is getting ready for some of that old time religion, also known as polytheism. To mark the Gods and Kings expansion, Firaxis and 2K Games are offering the game as free to play for this weekend, lasting from today until Sunday, May 27.
If your taste of ruling over kingdoms tempts you to buy the full game, this weekend is a particularly cheap way to do it. All of the Civilization V content on Steam is 75% off, which means the standard game can be had for $7.49. You could get the Cradle of Civilization downloadable content for $2.49, or the Game of the Year edition with extra maps and civilizations for $12.49.
The Gods and Kings expansion is scheduled for June 19 in North America. It will add religion and religious city-states, new diplomacy options with espionage, new scenarios, and a reworked combat system.
